SELECTIVE DUMP CAB.

The present invention relates to selective dump cars. v

More particularly the present invention relates to cars for depositing ballast along a railroad track either ,between'the rails, at

one side of the rails, at the other side of the rails, or in any desired combination of said regions'ofdumping. It is common todeposit ballast from a moving car, and for this purpose. cars have been provided. having dumping mechanism for permitting a flow of ball'astto the region betweenthe rails and for permitting avflow of ballast outside of. the rails. 'Ihe ballast cars are frequently operated in trains, and when one car'has deposited itsballast the operator will control anothercar to start the flow of ballast. f I I I In iballasting track simultaneously to the center and sides, conditions sometimes arise in which it is desirable to suddenly increase the amount of flow of material to the side,j while at the same timemaintaining a uni- 'track. 1 a 1, l r

An object of the present-invention, there fore, is to provide dumping mechanism which will permit the relatively uniform flow of ballast to the regionv between the rails) while .permitting. -a, quick increase through .wide variations .of the flow. of bah last to either or both sides. ofthe'rails, Y v

Mounted adjacent to the sills 22 are the inwardly sloping bottomwalls 55; Mounted in abutting re lationship with the sills 3'3 are the outward-1y sloping bottom walls 66. Each pair of walls 5 and 6 is controlled by a door member indicated by the numeral, 7, each of which doors 77 is of compound construction, as willbe more fully referred to here inafter Each of saiddoors 7-7 is pivoted for swinging movement about a corresponding longitudinally disposed axis 8, being pivotally supportedby a, corresponding hinge plate 9.

The numeral 10 indicates a shaft extending longi tudinally of the car, which shaft hasnon-. rotatably mounted thereon the crank member 11,; havingthe two crank arms 12 and j 13. The crank arm 12 is connected through the two short links 14 and 15 tothe lever armv16, which is connected to the swinging extremity'of the left hand door 7 as the parts are viewed in Figures 1 and 2. The crank arm 13 is connected through the links 17 and *18'with1the leverwarm 19, which lever arm 1 19 is connected to the swinging extremity of claimedin the present application for the link mechanism by means of whichthe shaft 11 controlsthedoors 7--7. It will be un-- derstood that when the shaft 10 is turned in one direction the doors 77 will be gradually moved toclosed position. Rotation with the shaf t 10 in the opposite direction will result in the gradual opening of the doors 7- Forproviding the relatively slow ad-l justrnent of shaft 10-,-said shaft may be pro.-

10" and shaft 10 have been omitted from .l ie'ure 11. for purposes of clearuess. The ad vintage of this relatively line adjustment for dumping; between the tracks will be clear, inasmuch as the amount of ballast ordinarily required to be deposited between the tracks quite uniform and inasmuch care should be taken not to llood the rails. W'hen one car after another of a train to be dumped, the line adjustment permitted by the illustrated mechanism permits the oporator or operators to start an easy flow of ballast to the region between the tracks at the time that the last portion of the ballast is bring deposited from another car of the train.

Each of the doors 7*"? is provided with a hinged intermediate closure 20, each of said (YlOFtlUQS being; hinged along longitudinal axes 2l-i?.l. Said interi'ncdiate closures --90 are nulcpcmlently operable and control the tlow of ballast laterally of the rails upon which the car is mounted. For the purpose of controlling the closures 20--20, each ot said closures is provided with a flexible connector 22. which extends over the swinging edge of the corresponding closure 90 and which is adapted to be wrapped up upon the corresponding longitudinally extending shaft 23. Preferably the pitch line of each chain 22 should extend through the axis 8 of the correspoiuling swinging door 7.

Fi ti'ires El and t illustrate mechanism for eontrolliim the rotation of either of the shafts 523 to control side dumping. Referrino to Figure 4-, it will he noted that the shale 23 is provided with the ratchet member .l-lotatably mounted upon the shaft is the ratchet lever 26, which has pivoted :herc'to the pawl 22'. The pawl 27 is adapted in certain positions of the ratchet arm .26 to engage the teeth of the ratchet member and to comnuu'iicate rotative movement to shaft 23. As shown in Figure 4, the pawl 27 may readily be thrown out of operative engagement with the ratchet Also mounted upon each of the shafts is the ratchet plate having teeth. 29-29 projecting from the opposite faces thereof. Said teeth 29 have abutting faces 30 extending in planes substantiz'illy parallel with the axis of the shaft and have beveled faces 31. Pivotally mounted adjacent to the shaft 23 is the bifurcated detcnt member 32, which detent member has the socket portion 33 for the reception of a rod. Said detent member 32 is rotatably mounted upon the pivot 23% and is provided with the two jaw members which are positioned to embrace the edge portions of the ratchet plate 28. The teeth 29 29 and jaw members 35 are so coordinated that when the correspondingdoor is being closed, the beveled portions of the teeth 2929 will cause the reciprocation of the detent member 32 about the pivot 3 f, permitting closure of said door 20. Goopeation between a jaw member and the unbeveled face 30 of a tooth 29 will hold the corrcsponding door in the position to which. it has been moved. When it is desired to permit the opening of the corresponding door 20, the detent member may be oscillated about the pivot. 3%, whereby the corresponding door will be allowed to move rapidly in a step-by-step movement to the open position desired by the operator. It will be understood, of course, that after the ratchet lever :26 has moved the corresponding door 520 to the desired closed position, the pawl 27 may be moved out of cooperative relationship with the ratchet- 25, whereby to permit the ready opening of the corresponding door .20 by means of the detent member 32.

It will be clear without. detailed explanation that a dump ca r or a train of dump cars may be moved along; a track at the required rate and that dumping may be controlled with relatively uniform adjustment for depositing the required amount of lading between the rails without flooding said rails. For depositing hiding outside of the rails, where a sudden increase in the flow may be desired. the illustrated mechanism permits the ready control of the flow through a relatively wide range, as required by the conditions along the track.

'lhoug'h certain preferred mechanism for providing relatively fine adjustment for center dumping has been illustrated and though certain preferred mechauisi'n for permitting rapid changes in the rate of flow for side dumping have been illustrated, it is clear that other mechanisms l'iaving these functions may be employed without departing from the spirit of the present invention.

lVhat is claimed. is:

1. In a railway dump car, in combination, means providing a pair of laterally disposed hopper bottoms, closures for said bottoms, means for operating said closures to permit dumping between the rails upon which said car is mounted, and means for controlling said closures to permit dumping laterally of said rails simultaneously with said dumping between the rails, said center dumping control means having a relatively uniform adjustment, said control means for dumping laterally of said rails being such as to permit rapid changes through a relatively wide range in the flow of dumpable material.

2. In a railway dump car, in combination, doors for discharging the load between the rails and doors for discharging the load outside the rails, operating mechanism for the doors discharging between the rails, said mechanism having a relatively uniform adjustment, and other operating mechanism lllll ill) for the doors discharging Outside the rails, said mechanism having a rapidly variable adjustment.

3. Ina railway dump car, in combination, side Walls, center sills, means for dividing and shedding ballast to the two sides of said center sills, doors pivoted along axes adjacent to said side walls for delivering bal last between the rails upon which the car is mounted, said doors being provided with intermediate closures for delivering lading outside of said rails simultaneously with the delivery of ballast betweensaid rails, control means for said doors having a relatively uniform adjustment whereby the flow of ballast between said rails may be nicely adjusted, and control means for said closures having a relatively rapid adjustment whereby irregularities in the regions outside of said rails may be readily compensated for.

4. In a railway dump car, in combination, doors for discharging the load between the rails, doors for discharging the load outside of the rails, operating mechanism for the doors discharging between the rails, said mechanism having a relatively uniform adjustment, and other operating mechanism for the doors discharging outside of the rails, said other operating mechanism including mechanism for controlling the opening of said last mentioned doorsunder the influenceof the load within said car, said other operating mechanism also including ratchet mechanism for raising said last mentioned doors against the influence of gravity, said ratchet mechanism being adapted to be rendered inoperative.
